# Golang program for implementation of Pancake Sort

Pancake sorting is the colloquial term for the mathematical problem of sorting a disordered stack of pancakes in order of size when a spatula can be inserted at any point in the stack and used to flip all pancakes above it. A pancake number is the maximum number of flips required for a given number of pancakes. Here is source code of the Go Program to implement Pancake Sorting Algorithm.

### Example

```
``````
package main
import "fmt"
func main() {
list := data{28, 11, 59, -26, 503, 158, 997, 193, -23, 44}
fmt.Println("\n--- Unsorted --- \n\n", list)
list.pancakesort()
fmt.Println("\n--- Sorted ---\n\n", list, "\n")
}
type data []int32
func (dataList data) pancakesort() {
for uns := len(dataList) - 1; uns > 0; uns-- {
// find largest in unsorted range
lx, lg := 0, dataList[0]
for i := 1; i <= uns; i++ {
if dataList[i] > lg {
lx, lg = i, dataList[i]
}
}
// move to final position in two flips
dataList.flip(lx)
dataList.flip(uns)
}
}
func (dataList data) flip(r int) {
for l := 0; l < r; l, r = l+1, r-1 {
dataList[l], dataList[r] = dataList[r], dataList[l]
}
}
```

### Output

```
``````
--- Unsorted ---
[28 11 59 -26 503 158 997 193 -23 44]
--- Sorted ---
[-26 -23 11 28 44 59 158 193 503 997]
```
